Do not call people, that will sound as needy.

Ask from whoever is in charge of the elections (some teacher or principal) for approval to put up posters. That way students will be constantly reminded that you are running for Vice President.

Ask students what they want changed. And not something like “let’s get out of school earlier” but something more like a change in cafeteria food or if they need new history books for 7th grade. Try to make it casual and show them that you care about them. You don’t need to make a great speech to show that you are the one (although if a speech is required by all candidates, make sure you act CONFIDENT! No one wants to vote for somebody who talks softly and seems scared….they want a leader). I hope you’re in seventh or preferably eighth grade…talk about how you’ve been in the middle school for a while, how you know your way around and how you see areas of the school that need improvement (like for example…not enough art supplies for art classes or something)

Good luck on your campaign!
